yii查詢資料分組統計

$query=Information::find()->groupBy('insertion_time')->alias('a')->select('count(*) as total,a.*')->all();

本地正常，但放在線上就報錯，所以就用原生SQL去查詢

$sql = "SELECT count(*)as total,insertion_time FROM `tre_information_hints` GROUP BY insertion_time";
$query = Yii::$app->getDb()->createCommand($sql)->queryAll();
 
 
 
-------------------------------------------------------------------------------------------
select from_unixtime(created_at, '%Y-%m-%d') AS time,count(DISTINCT user_id) as mun from tre_mineral_log GROUP BY time ORDER BY time desc

total是自己定義的欄位存放統計數目。
